Re: mic to speaker (megaphone)

I may be a bit late but might be able to clarify a few things anyway. Why don't you just get a portable, battery-powered amp with a mic input and speaker outputs? The Pi's sound output quality is pretty bad and probably not powerful enough to drive proper speakers anyway. (In fact, you would typical...

Re: Raspberry pi as FLAC audio player (with screen)

I would use MPD (well, I'm actually using it in my setup) and install ympd on the side. (A very lightweight webserver/MPD client.) You would then simply point the Pi's browser to localhost in order to queue/play/pause MPD. In fact, a web-based interface has the advantage that you could access it fro...

Re: EmulationStation - an emulator front-end

I read everywhere I had to go here: /boot/config.txt; to change something, but I don't understand how I should do .. where do I enter this command? Depending on what HDMI mode is being used, uncommenting hdmi_drive=2 in /boot/config.txt will solve your problem. At the terminal prompt, type: sudo na...

Re: MAME4ALL for Pi

E.g. if the native game resolution is 288x224 and my VGA output is set to 640x480, then resolution=320x240 fixes the problem and every game pixel is exactly 2 VGA pixels. mame4all will stretch the 320x240 over 640x480 but not stretch the 288x224 to 320x240. Instead I get the 288x224 pixel perfect w...

Re: A newbie looking to turn my Pi into an Emulator

Ive heard that certain USB devices require and external power source with the pi. Is that right?
Not any controller I've used so far. (I don't think any controller would draw that much current.)

Re: PiNoir, infrared light, IR lenses and purple images

I've also found AWB results to be varying, yet don't want to set WB manually as lighting conditions are likely to change during the day and I would like things to run without having to change settings all the time. That being said, it may prove worthwhile to simply turn saturation all the way down a...

Re: Sound issues with Pure Data / Jack

Went thru something similar... Can you post your .pdsettings file? What sound device do you use? Cases in which I noticed problems before, include: a too slow SD card, having set the no. of input channels to 2 i.s.o. 1 when using a UCG102 (this really messed up the sound), keeping the USB speed at 2...

Re: USB Soundcard Prevents Boot

Finally managed to put some more time into this. In short, only one thing helped (tried all suggestions, though): a new class 10 SD card... (The old one was slower, like class 4 or so.) That's using ALSA, though, and not Jack. Haven't had the time to try that...

Re: USB Soundcard Prevents Boot

A few seconds after having started Pd (and at other, seemingly random times) I still often get a real fuzzy, almost square wave-like, sound. I seem to be able to work around it by "sudo renice"-ing the jackd and puredata processes, i.e. giving them a higher prio. This seems to results in no sound ar...

Re: USB Soundcard Prevents Boot

I'm having the same issue (I think). So: the Pi works fine with my E-MU 0404 (just like that). The UCG102 (clone) works fine in Windows but on the Pi it doesn't. I'm using the simplest of Pd patches (adc~ to dac~) and when I play a note it comes out all distorted/scratchy sounding. Tried 44100 and ...

Re: EMULATION ON THE RPi (UPDATE)

If you're seeing the white dot/kick out behavior for certain (but not all) emulators after reinstalling the RetroPie script, you might have to change some 1s to 2s in ~/.emulationstation/es_systems.cfg for RetroArch-based emulators. See http://www.raspberrypi.org/phpBB3/viewt ... 40#p335640.

Re: My experience getting Emulationstation up and running

Regarding my earlier comment on my N64 controller(s). I just installed the latest RetroPie and binaries and now things work. However, upon starting EmulationStation for the first time, during the initial controller setup, it sort of skips the 'up' and 'left' button, and they end up as 'type="hat"' i...

Incorrect N64 controller behavior in EmulationStation

Hi all! Set up N64 controller (using a Mayflash USB adapter) on the RPi just fine in both ES and RetroArch. Works perfect in-game, but browsing games doesn't work as well. With the first game in the list highlighted, when I press the down button the selector jumps to the third game. Press it again, ...
